Inspection Procedure

  1. INSPECT DOOR OSCILLATOR 
    1. Disconnect the oscillator connectors.
    2. Measure the voltage according to the value(s) in the table below.

      Voltage: 

      Front LH side 

      TESTER CONNECTION SPECIFIED CONDITION

      Tester Connection Condition Specified Condition
      W1-1 (+B) - W1-7 (GND) Always 10 to 14 V

      Front RH side 

      TESTER CONNECTION SPECIFIED CONDITION

      Tester Connection Condition Specified Condition
      V1-1 (+B) - V1-7 (GND) Always 10 to 14 V

      Rear LH side 

      TESTER CONNECTION SPECIFIED CONDITION

      Tester Connection Condition Specified Condition
      Y1-1 (+B) - Y1-7 (GND) Always 10 to 14 V

      Rear RH side 

      TESTER CONNECTION SPECIFIED CONDITION

      Tester Connection Condition Specified Condition
      X1-1 (+B) - X1-7 (GND) Always 10 to 14 V

    NG: REPAIR OR REPLACE HARNESS AND CONNECTOR

    2. Measure the resistance between the oscillator and the certification ECU to check for an open circuit in the wire harness.

      Resistance: 

      Below 1  

    3. Measure the resistance between the oscillator and the certification ECU to check for an short circuit in the wire harness.

      Resistance: 

      10 k or higher 

      HINT:

      Refer to the WIRING DIAGRAM  for connection of each terminal.

    NG: REPAIR OR REPLACE HARNESS AND CONNECTOR

    OK: GO TO NEXT STEP 

  3. PERFORM ACTIVE TEST BY INTELLIGENT TESTER (CERTIFICATION ECU OUTPUT SIGNAL) 
    1. Reconnect the ECU and the oscillator connectors.
    2. Connect the intelligent tester to the DLC3.
    3. Turn the engine switch on (IG).
    4. Following the display on the tester, select the "ACTIVE TEST".

      Certification ECU: 

      ECU CERTIFICATION CHART

      Item Vehicle Condition / Test Details
      D TRANSMITTER Door Oscillator ON / OFF
      P TRANSMITTER Door Oscillator ON / OFF
    5. Measure the frequency according to the value(s) in the table below.

      OK 

      TESTER CONNECTION SPECIFIED CONDITION

      Tester Connection Condition Specified Condition
      D39-33 (CLG1) - D39-34 (CG1B) During ACTIVE TEST Frequency is generated (higher than 0 Hz)
      D39-35 (CLG2) - D39-36 (CG2B) During ACTIVE TEST Frequency is generated (higher than 0 Hz)
      D40-8 (CLG3) - D40-9 (CG3B) During ACTIVE TEST Frequency is generated (higher than 0 Hz)
      D40-10 (CLG4) - D40-11 (CG4B) During ACTIVE TEST Frequency is generated (higher than 0 Hz)

    OK: PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN  PROBLEM SYMPTOMS TABLE

    NG: GO TO NEXT STEP 

  4. REPLACE DOOR OSCILLATOR (CHECK OPERATION OF DOOR OSCILLATOR) 
    1. Replace the door oscillator.
    2. Check that the entry LOCK / UNLOCK function operates normally.

      OK: 

      Entry LOCK / UNLOCK function operates normally. 

    NG: PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN  PROBLEM SYMPTOMS TABLE  

    OK: END (DOOR OSCILLATOR IS DEFECTIVE)
